Fast moving images in my head?

[Cicero]

So I never really gave much thought to this now that I'm older, but years ago I would experience fast movies images in my head. Not just random images, but specific ones, (I forgot what they were, I have a small hunch of what I think they were, but it'd be so randomly weird to say) and the images would last but a few seconds in reality. Yet in my head they seemed to last for a few minutes, what I would remember is something like talking. Like fast talking but slow enough that I could understand it. It would kinda creep me out and I noticed when it would happen, it was like I was daydreaming, but I wasn't.

What do you think it was and has anyone else experienced this?

I really found it strange, but I never told anyone cause it was both hard to explain and just really weird sounding.

If its not happening anymore then i wouldn't worry. Might be called hypnopompic dreams but that's just a guess
